The track thrust'surface on t e flange 1'5,.mmate 1 number is positioned upon the supporting sliding friction between the slide track member 2 so that the heads of the studs 4 member at the u per end the s o extend thro h the enlar ements of the slide is provide with a pm 21 at gml 3 an are then mov cd to the left so which are adapt ll to engage' the ends of the 309 e r 0 t t the shanks 5 lie in the smaller portlons bar 19 after the 81166 has moved a predict 6 of the'openings, whereupon the track mcmmined distance and csrry seid bar andv the anti-friction devices 17 along with it. The track is also provided with pins 22 at each end. which, after bar"l9 has bcenmoved a certain distance in one direction or the other, prevent its further movement and also block the continued ovement of the slide. Between the track Wand the opposing surface of the flange 16 a similar antifriction device to that shown in Fi sfiand 6 is also placed, being supported by t e horizontal track 13, the axes of the anti-friction members being also vertical as shown in dots in F ig. 2. Upon the horizontal track 13 are also placed short c 'lin dri'cal rollers 23, one on each side of the device shown in Figs. 5 and 6 'so as to be spaced apart by the member 1 which rollers engage the horizontal track and also engage the horizontal undersurfacc on the bottom of the Z, thus supporting the slide. The united anti friction rollers 17 and the rollers 23 at the bottom of the slide'thus eliminatesliding friction between the slide and track at that point, the rollers 23 supporting the slide and resisting its downward thrust at two points, while thelrollers 17 with their vertical axes resist the side thrusts at two points. Pins 21 and 22' confine the anti-friction devices at the lower edge of the slide acting in a manner similar to pins 2land 22. The slide is provided with ears 24, to which is secured the frame of the carriage proper, which may be of any desired construction.- The slide carries a plate 25 which supports a pin 26, which acts as a stop for the slide and carriage, limiting the movement of the same by engaging the side plates 27 of the carriage when the same has reached its proper limit in either direction.

In constructing the machine the parts are assembled as shown, whereupon the slide with the carriage supported thereby is free to move in one direction or the other without sliding friction, the rollers 23 resisting the downward thrust while the rollers 17 at top and bottom resist the side thrustt' With the Z-shaped slide thus guided and supported, the slide can be made of sheet metal. with resulting simplicity and cheapness in manufacture and accuracy in result.

As will be evident to those skilled in the art, my invention permits of various modifications without departing from. the spirit" thereof or the'scope of the appended claims.

What I claim is: j A

1. In a machine having a sliding carriage, the combination of a track member having at its top an overhanging flange andgat its bottom upwardly pro ecting retaining means, a slide therein havin at its upper and lower ends oppositely acing vertlcal surfaces and having at its lower port-ion a downwardly facing surface adjacent to the upperedgo of the lower vertical surface, in combination with side-thrust anti-friction members between said vertical'surfaces and sa d track member, and sup iortin'g antifriction members between sex downwardly facing surface and said track member, the upper end of said slide tending to move toward the overhanging flange.

5g, In a machine having a sliding carriage, the combination of a track member having at its top an overhanging flange and ata'ta bottom upwardly projecting retaining means, a slide therein having at its up er and lower ends oppositely facing vertica surfaces and having at its lower portion a downwardly facing surface adjacent to the upper edge of the lower vertical surface, in combination with side-thrust anti-friction members between said verticalsurfaces and said track member, ind su porting anti-friction members between sa. d downwardly facing surface and Said track member, the upper end of said slide tendingito move toward the overhangin flange, t e side-thrust members beng to era havin vertical axes, and spacmg means for sai rollers.

3. In a machine having a sliding carriage, the combination of a. track member having at its overhanging .flange and at its bottom u wardly means, a sli' e therein havin at its up or and lower ends oppositely acing vertical surfaces andhevin'g at its lower portion a downwardly facin surface adjacent to the upperedge of the ower vertical surface, combination with side-thrust anti-hictioh members between said vertical, surfaces and said track member, and an orting antifriction members between safd downwardly facing surface and sa'id track member; the upper end of said slide tendin ,to'move toward the overhan ng-flan'ge, t e side-thrust members being rofilers having vertical'aiee and the supportin members being rollers having lon itudina axes, and spacing means for Silld ro lers. h i i 4. n a machine having a s 'dmg' carria the combination of a track member hafi at its toll an overhanging flange and 8, its bottom upwardly means, a slide therein having and lower ends oppositely .surfaces' and having at its lower portion a at its upper acing vertical,

downwardly facing surface adjacent to the upper edge of the I combination 'with side-thrust anti-friction members between said vertical surfaces and said track member, and so porting'anti-friction members between sai downwardly .-facing surface and said track member, the upwe'r vertical surface, in

per end of said slide tending to \tnove to? ward the overhanging flange, ried by the ends of said track member and slide coacting with said anti-friction mem bers..

In a devi having a slidin carriage,

the combination of a track mem er having 1 at its top a depending flange forming a. yetand stops car i i tical track and at its lower part a surface forming a vertical track facing in the opposite direction from said first-mentioned track, and a horizontal surface forming a 5 horizontal track with a Z-shaped sheet metal slide having on its to and bottom flat surfaces, the lower sur ace being above said horizontal track, and at its extremities vertical portions parallel to said vertical tricks respectively, and anti-friction members be- 10 tween said vertical portions and said vertical tracks and between said bottom surface and said horizontal track.
